Filter by:Informal caregivers provide a majority of care for patients at the end of life. Lack of end of life preparation and completion may leave caregivers less capable of caring for a loved one or making crucial decisions influencing care. This study will examine whether a preparation and completion intervention reduces caregiver anxiety, depression, anticipatory grief, and burden and improves patient quality of life and health care use
Pulmonary hypertension (PH) can be the result of various clinical conditions. It may be idiopathic or associated with various cardiovascular and lung disorders. Currently there is no test that can non-invasively detect abnormalities of the pulmonary circulation. There is a growing need for a non-invasive method to detect PH. There currently exists only ne agent approved in Canada for clinical imaging of the pulmonary circulation, 99mTc-labeled macroaggregates. This agent is exclusively used for the diagnosis of physical defects of the circulation due to pulmonary embolus. This agent is larger than small pulmonary vessels, limiting its sensitivity to detect small vascular defects, as well as potential infectious risks since albumin macroaggregates are derived from human albumin. There is need then for new lung tracers that could provide a greater safety profile while enabling functional as well as anatomical imaging of the pulmonary circulation. DFH-12 (PulmoBind) is a peptide derived from human adrenomedullin (hAMI-52). Hence the development of this novel AM derivative, PulmoBind, for molecular imaging of the pulmonary circulation. PulmoBind is labeled with 99mTc, the most commonly used imaging isotope in nuclear medicine.
Inhaled nitric oxide in preterm babies with respiratory failure or ventilator dependence will: 1. decrease the incidence of Bronchopulmonary Dysplasia (BPD) or death 2. shorten the length of oxygen therapy and hospital stay ,reduce the cost of hospital stay without increasing adverse effect
This project will evaluate the effects of World Trade Center (WTC) exposure in WTC responders 10-13 years following the events of 9/11. Prior studies have described persistent pulmonary function abnormalities in a significant portion of responders. The investigators study seeks to examine the relationship between pulmonary function abnormalities and other markers of chronic cardiopulmonary disease and further elucidate the pathophysiologic effects of exposure to inhaled particulate matter (PM) on 9/11. This study will provide critical information regarding risk of exposure to PM, risk factors for disease and potential for improvements in diagnosis and treatment.
To demonstrate the additional benefit of roflumilast when added on to fixed-dose combination (FDC) LABA/ICS in the reduction of exacerbations in subjects with severe to very severe COPD.
The objective of this work is to investigate and then to sequence new biomarkers in the plasma of patients presenting with dyspnea secondary or not to heart failure, and study their diagnostic and prognostic value.
Heart failure with preserved ejection fraction (HFpEF) accounts for over 50% of heart failure cases in the United States, affecting a primarily elderly population. No treatment has been shown to affect mortality in HFpEF, which is more than 50% at five years a hospitalization. This project explores the underlying cardiovascular physiology of patients with HFpEF with the goal of identifying new therapeutic targets that would allow improved treatment of this devastating disease.
The aim of this study is to assess in the sample of population resident in the KHUMBU valley (NEPAL): 1. the respiratory function decline by means of spirometry and the respiratory health by means of questionnaire and six-minute walking distance 2. the presence of markers of early atherosclerosis with ultrasound and to estimate the value of systolic pulmonary pressure in comparison with not exposed subjects. The investigators hypothesize that the chronic exposure to indoor pollution 1. can accelerate the physiological respiratory function decline, usually around 15-20mL/year in healthy subjects 2. induce cardiovascular impairment The population of high altitude villages is a unique sample to study the effect of the only indoor pollution. In fact, the absence of traffic, due to the lack of roads, and the very low level of smoking habits allow to have no other confounding factors 3. to study and analyze how the architectural features of the buildings of the village (distribution of domestic locals, natural or non natural ventilation systems, domestic activities, materials used, etc.) affect the indoor pollution from carbon monoxide, which necessarily is developed indoor during the daily life activities. What the project prospects is to gather information focused on the scale of the building, independently from the typology, to study a model that will help to describe which aspects are most important to what concern the genesis of the pollution of the indoor air.
HIV-infected patients have an increased incidence of emphysema compared to non-HIV-infected patients, and it has been hypothesized that this accelerated disease progression is the result of one or more latent infections that amplifies the pulmonary inflammatory response. The investigators will examine the prevalence and progression of emphysema in subjects with and without HIV and determine risk factors for emphysema in this population.
Establishing new biochemical markers in the differential diagnostics and risk stratification in heterogeneous patient collectives is becoming more and more important. The markers should be objective, reliable, reproducible, quick and cost effective as well as specific and sensitive. Concerning the differential diagnostics of "dyspnea", NT-pro-BNP plays the most important role for the evaluation of a cardiac origin. However, a corresponding biochemical marker for pulmonary stress is lacking. The aim of the study at hand therefore was the evaluation of surfactant protein B in the differential diagnostics of pulmonary and cardiac diseases.
